I am serious. And no you dont need to go back to 1942 either.
Remember the BBC during the Falklands?
Additional information that did not need to be published not only told the Argentinians their bombs were not exploding, but went on to give them the bloody solution.
Images posted of US patriot sites shared online within hours of deployment, not hard to get a grid on that.
Yes, i accept that we live in a digital information age and stuff is "out there" but don't hand it over on a plate!
Like I said, some folk need to rethink the "potentially" useful information they share willy-nilly from the comfort of their man-caves.
